Dear all, Thank you all and a big apology. I had missed a connection at one point and missed 2 wire connections to the ecf 80. Now everything is very close to normal i.e less than 10% out on voltage.
Playing well so will give all the new caps etc a chance to run in.
Thank you again for all your help and dare I say inspiration and help to take on something that is way outside my field.
Kind regards, Jiten.
